SPECIEJLCATION forming part of Letterslatene No. 712,655, dated November 4, 1902.

Application filed J'nly 2, 1902. Serial No. 114,098.' (No model.)

To @ZZ whom, it, may concern: j j j Be it known that we, CHARLES J. CCULTER and NILS F. ADAMSON, citizens of the United States, residing at Denver, in the county ofl Arapahoe and State of Colorado, have inventf ed certain new and useful Improvements in i Vrenches; and we do hereby declare the. fol lowing to'be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wrench-machines, and more especially to that class thereof known as bolt-holding,wheren the nut or the bolt is held by the mechanism while the nntl is being applied to or removed from the bolt. l

The object of the invention is to improve the details of construction of machines of this character in order to produce one in which bolts can be quickly applied-as, for instance,to railway-rail joints, inconnection with which itis illustrated in the accompanyi ing drawingsto which end the invention consists in the details set forth below and more particularly pointed out in the claims appended, allas shown in-the accompanying drawings, wherein- Figure 1 is a plan view, and Fig. 2 an end view, of lthis machine in use.` Fig. 3 is a side"` View, partlyin section. Figa is a transverse sectional view, and Figs. '5 and 6 are sectionalV details. r

Referring to the drawings, 16 designates the rail, mounted on ties, as usual, and the eX-C tremities of the rails are lappedby fish-plates in the well-known manner, and 17 is the customary bolt which passes through said plates and rail endsand receives a nut. The propo sition is to apply these nutsto the bolts in a rapid and effectual manner, more so than by hand, which is now the usual practice. We do not, however, limit ourselves to this use of the machine described below, though for purposes of illustration the same is shown 5 is the body, which isan L-shaped casting of sufficient length to cover'` all the bolts at The top of this body` stands abovethe tread of the rail andmay have rollers 5a, so that itcan be moved longitudinally thereon, with ease. The upright side of this body is preferably divided into ngers, as best seenin Fig. 3, the two outermost fingers carrying bearings 7 for a yoke 8, describedbelow, and the two innermost iingerscarrying a bearing or bearings 6, also for a purpose to appear below.

13 designates an upright clamp passed through an` aperture in the top of the body `5. 15 designates bearings rising from said body and in which is mounted a cam-shaft 14, having a handle 14 at a suitable point and a cam 141Ca preferably between said bearings, and this cam when turned by the camshaft presses the upper end of the clamp outward and throws its lower end inward, whereby it not only presses against the head of the bolts 17, but also clamps the body upon the rail. The latter, it is understood, may be any member through which it is desired to -insert the bolt.

The bearing 6, carried by the innermost `fingers of the body, supports a main or driven shaft 9, having at-its inner end a cup 9", shaped to receive the num-and at the bottom .ofsaid cup is a recess or depression 9c to receive the threaded end of the bolt when the nut has-been screwed thereonto. This shaft i stands in axial alinement with the axis of the bolt, being mounted in` its bearing 6 at -a `point to correspond with the height of the ,bolt and being moved-longitudinally, so as to correspond with the linear disposition of the bolt.

10 is the power-shaft, having rotary means, such as a crank-handle 12, at its outer end,

andthese may be disposed as preferred, so `long as they impart rotary movement to the main shaft, but as the latter when employed on railway-rails is rather low we preferably `make useof the following mechanism.

`at its outer end by which it may be turned.

The leg 19 usually raises theouter end of this shaft so high that some form of iiexible joint is needed between the inner end of the power or driving shaft and the outer end of the IOO ' ball-and-socket joint, although it is to be understood that any form of flexible joint which will answer may be used at this point without departing from the spirit of our invention..

By special reference to Figs. 5 and 6 of the drawings it will be seen that 10L designates a socket at the inner end of the power-shaft 10, through which socket passes transversely a pin 20. At the outer end of the driven shaft v9 is a head or ball 9a, through which is formed a peculiarly-shaped hole 20a, which is exactly round at the center of its length, where it fits closely around the pin 20, and is slotted at each end in a plane through the axial center of the shaft 9, its walls curving outward from its center toward each end, as best seen in Fig. 5. This permits flexible movement in all directions of one shaft 9 with respect to the other, 10, yet causes the former to be rotated by the revolution of the latter no matter what the angle between the two Within prescribed limits.

In use the machine is adjusted over the rail-joint where the bolts are to be applied, the bodies of these bolts having first been inserted through the fish-plates and the rail ends and their nuts applied. The cam 14Ca or other locking means is then adjusted, as will be clear, to push the bolt-bodies into place and to lock the machine in position. The yoke 8 is then raised to such a height that the crank 12 may be rotated without bringing the operators hand into contact with the ground or the ties, and the leg 19 holds it elevated. The main shaft 9 is then slipped forward through its bearing 6 until its cup engages the nut, and thereafter the crank 12 is turned in the proper direction to screw said nut onto the threaded end of the bolt-body, its tip passing into the recess 9c, as will be clear. The handle 14" is then manipulated so as to move the cam and loosen the clamp 13, after whichthe entire body is slid along the rail (on the rollers 5a, if employed) until the cup comes opposite anothernut, when the operation is repeated. It is obvious that the machine may be used for tightening nuts that are simply loose instead of beinginitiallyapplied and also that by reversal of the movement of the crank 12-the machine may be employed for removing nuts.

We do not desire to be limited to the precise details of construction, nor to the use of all the features herein set forth at one and the same time. It is clear that the rollers might be omitted, other forms of clamp could be employed, as well as other forms of liexible joint or even gearing between the two shafts, and various changes could be made in the details or in the proportions, shapes, or the materials of parts without departing from the spirit of the invention.
